- —Jon Valor about Rip Hunter[src]
At some point of time, Jon Valor became the leader of a group of Time Pirates, capturing time-traveling space ships and acting against the interests of Time Masters. During his activity as a time pirate, he learned of Rip Hunter's reputation as a member of Time Masters.
After receiving a distress call from another timeship stranded in space, Rip Hunter's team decided to answer the call in order to take over the other ship and use its computer to track Vandal Savage. The distress call came from Eve Baxter, another Time Master. When the team managed to her ship, they found out that it's been assaulted and taken over by Time Pirates, who used it as a bait to capture other unsuspecting vessels and prisoners.
With Rip Hunter imprisoned, Valor decided to take control of the Waverider, contacting Ray Palmer, who was left in command by Rip. Seeing the opportunity, Rip gave Gideon a secret voice command to activate defense protocols, saying "He once managed to outrun Kanjar Ro himself". The Waverider fired back and lead the Acheron on a pursuit, which ends up damaging the Waverider.
Mick Rory, angered by Rip, called out to the Time Pirates to cut a deal with Valor, who freed him and gave a squad of Time Pirates to capture the unsuspecting Waverider. Tired with Rip Hunter's stalling for time and confident in Mick Rory's ability to take over the Waverider, Valor tried to kill Rip, but the ex-Time Master and his team members under the guidance of Martin Stein initiated their trap and vented all of Valor's men out of the Acheron and into deep space.
